jQuery验证控件jquery.validate.js使用说明+中文API
一 导入js库
JS相关文件及演示demo下载
<!--依赖的jQuery库-->
<script src="../js/jquery-1.11.1.js" type="text/javascript" charset="utf-8"></script>
<!--validate校验库-->
<script src="../js/jquery.validate.js" type="text/javascript" charset="utf-8"></script>
<!--国际化库，中文提示（可选）-->
<script src="../js/messages_zh.js" type="text/javascript" charset="utf-8"></script>
二、默认校验规则
(1)required:true 必输字段
(2)remote:“check.php” 使用ajax方法调用check.php验证输入值
(3)email:true 必须输入正确格式的电子邮件
(4)url:true 必须输入正确格式的网址
(5)date:true 必须输入正确格式的日期 日期校验ie6出错，慎用
(6)dateISO:true 必须输入正确格式的日期(ISO)，例如：2009-06-23，1998/01/22 只验证格式，不验证有效性
(7)number:true 必须输入合法的数字(负数，小数)
(8)digits:true 必须输入整数
(9)creditcard: 必须输入合法的信用卡号
(10)equalTo:"#field" 输入值必须和#field相同
(11)accept: 输入拥有合法后缀名的字符串（上传文件的后缀）
(12)maxlength:5 输入长度最多是5的字符串(汉字算一个字符)
(13)minlength:10 输入长度最小是10的字符串(汉字算一个字符)
(14)rangelength:[5,10] 输入长度必须介于 5 和 10 之间的字符串")(汉字算一个字符)
(15)range:[5,10] 输入值必须介于 5 和 10 之间
(16)max:5 输入值不能大于5
(17)min:10 输入值不能小于10
三、默认的提示
messages: {
required: “This field is required.”,
remote: “Please fix this field.”,
email: “Please enter a valid email address.”,
url: “Please enter a valid URL.”,
date: “Please enter a valid date.”,
dateISO: “Please enter a valid date (ISO).”,
dateDE: “Bitte geben Sie ein g眉ltiges Datum ein.”,
number: “Please enter a valid number.”,
numberDE: “Bitte geben Sie eine Nummer ein.”,
digits: “Please enter only digits”,
creditcard: “Please enter a valid credit card number.”,
equalTo: “Please enter the same value again.”,
accept: “Please enter a value with a valid extension.”,
maxlength: $.validator.format(“Please enter no more than {0} characters.”),
minlength: $.validator.format(“Please enter at least {0} characters.”),
rangelength: $.validator.format(“Please enter a value between {0} and {1} characters long.”),
range: $.validator.format(“Please enter a value between {0} and {1}.”),
max: $.validator.format(“Please enter a value less than or equal to {0}.”),
min: $.validator.format(“Please enter a value greater than or equal to {0}.”)
},
如需要修改，可在js代码中加入：
jQuery.extend(jQuery.validator.messages, {
required: “必选字段”,
remote: “请修正该字段”,
email: “请输入正确格式的电子邮件”,
url: “请输入合法的网址”,
date: “请输入合法的日期”,
dateISO: “请输入合法的日期 (ISO).”,
number: “请输入合法的数字”,
digits: “只能输入整数”,
creditcard: “请输入合法的信用卡号”,
equalTo: “请再次输入相同的值”,
accept: “请输入拥有合法后缀名的字符串”,
maxlength: jQuery.validator.format(“请输入一个 长度最多是 {0} 的字符串”),
minlength: jQuery.validator.format(“请输入一个 长度最少是 {0} 的字符串”),
rangelength: jQuery.validator.format(“请输入 一个长度介于 {0} 和 {1} 之间的字符串”),
range: jQuery.validator.format(“请输入一个介于 {0} 和 {1} 之间的值”),
max: jQuery.validator.format(“请输入一个最大为{0} 的值”),
min: jQuery.validator.format(“请输入一个最小为{0} 的值”)
});
推荐做法，将此文件放入messages_cn.js中，在页面中引入
<script src="../js/messages_cn.js" type="text/javascript"></script>
四、使用方式
1. 将校验规则写到控件中
<html lang="en">
<head>
<meta charset="UTF-8">
<title>title>
<script src="../js/jquery-1.11.1.js" type="text/javascript" charset="utf-8">script>
<script src="../js/jquery.validate.js" type="text/javascript" charset="utf-8">script>
<script src="../js/messages_zh.js" type="text/javascript" charset="utf-8">script>
head>
<body>
<form id="formId" method="post" action="">
<label for="username">请输入用户名:label>
<input id="username" type="text" name="username"/><br/><br/>
<label for="password">必填数字：label>
<input id="password" type="text" name="password"/> <br/>
<label for="repassword">必填重复：label>
<input id="repassword" type="text" name="repassword"/> <br/>
<label for="zuixiaozhi">最小值：label>
<input id="zuixiaozhi" type="text" name="zuixiaozhi"/> <br/>
<label for="shuzhiqujian">区间：label>
<input id="shuzhiqujian" type="text" name="shuzhiqujian"/> <br/>
<input type="submit" value="提交"/>
form>
body>
<script type="text/javascript">
$(function () {
$("#formId").validate({
rules: {
username: "required",
password: {
required: true,
digits: true,
},
repassword: {
equalTo: "[name='password']"
},
zuixiaozhi: {
min: 10
},
shuzhiqujian: {
range:[5,10]
}
},
messages: {
username: "不可以为空",
password: {
required: "密码不可以为空",
digits: "请输入数字"
}
}
});
})
script>
html>
2. 自定义校验规则(正则表达式),校验手机号码
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Titletitle>
<script src="../js/jquery-1.11.1.js" type="text/javascript" charset="utf-8">script>
<script src="../js/jquery.validate.js" type="text/javascript" charset="utf-8">script>
<script src="../js/messages_zh.js" type="text/javascript" charset="utf-8">script>
head>
<body>
<form action="#" method="post" id="myform">
<input type="text" name="phone" placeholder="请输入手机号码"/>
<button type="submit">提交button>
form>
body>
<script type="text/javascript">
//手机号码验证
jQuery.validator.addMethod("isMobile", function (value, element) {
var length = value.length;
var mobile = /^(13[0-9]{9})|(18[0-9]{9})|(14[0-9]{9})|(17[0-9]{9})|(15[0-9]{9})$/;
return this.optional(element) || (length == 11 && mobile.test(value));
}, "请正确填写手机号码");
$("#myform").validate({
rules: {
phone: {
required: true,
isMobile: true
}
},
messages: {
phone: {
required: "必填",
isMobile: "请正确填写手机号码"
}
}
});
script>
